Hey guys, a strange thing happens every time it gets hot outside (about 80 degrees or hotter). My T/A's engine starts to stutter violently while I'm idling at the speed limit or slowing down, unless I put my foot in it. The stranger thing is when it's under that temperature outside, it's fine. It has nothing to do with engine temperature, it's only ambient temperature that seems to bring on the "seizure". Any thoughts anyone?

88 T/A
305 TPI (LB9)

 

Mine did that and I found that the Ignition module connection to the stator assembly was loose - so I cleaned the connection and replaced the ignition module.
